I'm feeling my age. I'm at a festival for the first time since all that covid shenanigans (helping set up, so I get in free

). Today I erected 25 flags on enormously long scaffold poles .... 4 of them twice as the gaffa turned up half way through with some lead weights that were supposed to be added to the flags. Kinell!
Now I'm nursing aching limbs and a disgruntled back, listening to the test match, sipping some wine and my peace is being ruined by deaf sound engineer repeatedly playing the same droning, booming monotone techno bass track at around 120dB rattling my van. Its not a techno festival ffs.
How old is too old for this? Is it bad form to set a fire under a loudspeaker stack?
